Abstract/OtherAbstract:

OBJECTIVE: Self-poisoning with plant seeds or fruits is a common method of self-harm in South Asia. While most deaths follow ingestion of Thevetia peruviana (yellow oleander) seeds, other plants are locally common. During review of fatal injuries seen in a teaching hospital in eastern Sri Lanka, we noted cases of fatal self-poisoning with Cerbera manghas (sea mango, pink eyed cerbera, odollam tree) fruits. METHODS: We reviewed the post-mortem records of the Batticaloa Teaching Hospital and extracted data on all cases of fatal injury. RESULTS: During 2001 and 2002, 315 post mortems for injury were performed in Batticaloa Teaching Hospital. Intentional self-harm was responsible for 48.6% of cases. While T. peruviana was responsible for 33 deaths, C. manghas self-poisoning caused seven deaths. C. manghas cases had typical features of cardenolide poisoning with cardiac dysrhythmias and hyperkalemia. In the absence of pacing facilities and anti-digoxin Fab, management involved administration of atropine and of insulin and dextrose to lower serum potassium concentrations. CONCLUSIONS: C. manghas self-poisoning has only previously been reported from Kerala and Tamil Nadu in south India. While uncommon in other parts of Sri Lanka, it has become a common method of self-harm in one east coast district, accounting for 20% of fatal self-harm with plants in one hospital. Management was inadequate with the available resources, emphasising the need for an affordable antitoxin for plant cardenolide poisoning.
